This weekend's adventure: Cedar Creek Grist Mill outside of Woodland, WA.
It's the only mill in Washington that's retained its original structure, is powered by water and still grinds with stones (like this one!) . It's another "working" historical museum and the volunteers will tell you everything you ever wanted to know (and then some) about the history of grain farming in America, milling, why whole grains are so nutritionally important, and a great deal of local history. Then they fire up the creek-powered turbine and in seconds out comes finely ground flour, which they generously give to visitors (along with delicious recipes) to go home and make their own bread.
There's a beautiful covered bridge over the creek. Next weekend I'm told they make Native American Fry Bread on premises with the flour they grind themselves. Next month, it's apple-pressing time.
